In the hibernating ground squirrel activity of adrenal dopamine-beta-hydroxylase was significantly lower as compared with the active animals (P less than 0.01). The highest activity of this enzyme was found in animals tested immediately after arousal from hibernation (P less than 0.01). The adrenal weight was higher in hibernating animals than in the active or aroused ones. The difference between the active and aroused animals was significant (P less than 0.01). Extremely high enzyme activity was found in the adrenals of animals exposed to continuous light for 3 weeks as compared with active animals kept in continuous darkness or with controls subjected to a regime of 12 hr light - 12 hr darkness (P less than 0.01). The weight of the adrenals in the three groups was about the same level.
